Scantenna ST-2

[SLWilson]

I just recently put up a new Scantenna ST-2. Have it up about 25 feet on a standard TV type tower.

Before moving it UP ON THE TOWER, (it was mounted near ground level after being put together & the coax hooked up to it) I hooked the scanner to it to make sure the connections were good and the scanner would receive OK. It did. All bands.

Now that I have it "up off the ground" the scanner won't hear ANYTHING much on VHF-Hi or Low band....Unless it is within a few blocks of the house. Same on UHF.

Here's the CRAZY part. On 800Mhz Trunked radio, it seems to be hearing OK.

I've taken the scanner to another location that has the Scantenna model I have and it works great there on ALL bands.

What's up with that? (The scanner is a RS Pro2096)
Thanks,

Sounds to me like you may have a bad connection somewhere. Something may have happened during the move and mounting process. That's where I would look first.

The GRE scanners overload on VHF from LARGE antennas. The ST-2 is a large antenna. A more simpler tri-band antenna would work. Ck pvt msg.

ST2 Performance

I am currently using a 2m/70cm dual band 48" mobile antenna on a ground plane and am curious as to what gain may be involved on the ST2. With the current antenna I have 3db on vhf and 5db on uhf. Would there be any advantage to going with the ST2? I mainly scan 150-170 and 400-500. The local 800 trunk systems are so close that I am not really concerned with 800 performance but a bit more of omni gain on vhf-uhf would be cool. Anyone else experience any improvement from a similar upgrade?
